SOUTH DENNIS – A 19-year-old man was seriously injured in a dirt bike accident Saturday afternoon and was flown by medical helicopter to a Boston hospital, according to a fire official.

The man may have been attempting to jump his dirt bike over a large pile of dirt behind the Dennis Department of Public Works on Theophilus Smith Road before falling just after 5 p.m., Dennis fire Capt. Wayne Conlon said.

He suffered several severe injuries from the impact of hitting the ground, Conlon said, but none of them appeared to be life-threatening.

The injured man was taken in an ambulance to Nathaniel H. Wixon Innovation School where he was met by his parents and a MedFlight helicopter. He was then flown to Tufts Medical Center, Conlon said.

A fire official was seen carrying a helmet from an ambulance where the man was treated. An ATV was also at the scene but it was unclear if that vehicle played any role in the accident.

No other details were immediately available and the accident remains under investigation.
